PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 628,4.31, dated July 4,1899.

Application filed June 25, 1898- Serial No. 684,505. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM A. CLARK, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Plow-Points, ofwhich the following is a specification.

In different sizes and styles of plows the angle formed between theintersecting lines [0 of the share and the landside varies considerably,causing much labor in fitting when the worn point is replaced bya newone. The points commonly furnished blacksmiths for this work are formedon a certain angle, and

if upon trial this angle does not correspond with that of the plow thepoint must be fitted by heating and bending. This operation weakens anddistorts the point, besides taking much time in its accomplishment.

The object of this invention is to produce a plow-point which mayreadily be adapted to a plow of any angle, and this object isaccomplished by welding the share and landside together along a portiononly of their adjacent surfaces.

In the accompanying drawings, Figure 1 is a front elevation of aplow-base, showing one of my improved points attached thereto, dottedlines indicating the position of the un- 0 welded portion of thelandside. Fig. 2 is a rear side perspective view of a plow-point beforeit is fitted to the plow-base. Fig. 3 is a side elevation of the plow asshown in the preceding figure.

3 5 Like letters of reference indicate corresponding parts throughoutthe several views.

A is the plowshare. A is a projecting edge of the plowshare A.

p A are bolts for securing the point in posi- 0 tion on the plow-base.

B is the landside portion of the plow-point. The share and landside arewelded together along a portion only of their adjacent surfaces.

5 In fitting this point to a plow-base the point is placed in positionto ascertain if its angle agrees with that of the plow. If theycoincide, no fitting is required. If their angles do not agree and theupper line of the plowshare does not coincide with the lower line of themoldboard-following, for example, dotted line a: as of Fig. 1the pointis heated and the rear end of the landside B is bent outward until theplow-point fits the base. When the angle of the plow-point has thus beenmade agreeable with the angle of the base, the joint between thelandside B and the share A is closed by welding, the projecting edge Aof the share A is out off, and the holes formed for receiving thesecuring-bolts A If necessary, the rear end of the landside portion B iscut off until it forms a perfect joint with the forward end of thebalance of the share and landside being Welded together at a portiononly of their adjacent surfaces, whereby the angle formed between themmay be altered to conform the plow-point to the angle of a plow.

2. As a new article of manufacture, a plowpoint comprising share andlandside portions, the share and landside being welded together at aportion only of their adjacent surfaces, said point of attachment beingat or near the forward end of said landside, whereby the angle formedbetween the share and landside may be altered to conform the plow-pointto the angle of a plow.

8. As a new article of manufacture, a plowpoint comprising share andlandside portions, the share and landside being welded together along aportion only of their adjacent snrfaces, said point of attachment beingat or near the front part of said adjacent surfaces, whereby the angleformed between the share and landside may be altered to conform the 5plow-point to the angle of a plow.
